Ok, this question may be a little odd, but here it goes...I am wondering what the situation is with ordering and drinking tap water in Paris. I drink a lot of water, usually one large bottle or even more with a meal. The water must also have ice. Not very French of me, but that is what I like. I am not a fan of Evian, which seems to be the choice of 90% of restaurants (I am a Volvic fan). In a couple of weeks, I will be enjoying a few three star places in Paris, as well as some bistros (chosen in large part thanks to recommendations from Chowhounders).
I have two issues with the water: one is cost, the other is taste. When I ate at L'Arnsbourg last year, I literally spent over $50 on water; something about that just didn't seem right. Water is expensive at three-stars. So my question is: is it ok to order tap water in Paris? How does it taste? Is this considered a faux pas? Will the restaurant be offended? Is there a different answer to this question depending on wether I am at, say, Guy Savoy or at L'Ami Jean? As I said, I am not a fan of Evian, and if tap water is equal to or better than Evian, shouldn't I drink that instead?
